In this How To we are going to build NTP4.2.6p5 with our GCC 4.8.2 cross-compiler. Be sure to start this build in a new terminal/tab to avoid any pollution from previous builds.
Because the SBC's that I use, such as Raspberry Pi, Pandaboard, etc., do not utilize an RTC; NTP is a common workaround for keeping track of time. Maybe not the best but it works :-P
Tar Balls
Here is a list of source packages that we'll need for the build. You can either download them now or wait 'til later in the How To.
ntp-4.2.6p5.tar.gz
Create a Workspace
I recommend creating a workspace under your /home/<your user>/ directory that is dedicated to this build. So let's fire up your terminal and run the following:
NOTE: Depending on whether you are using a cross-compiler built from my other wikis you might need to change INSTALLDIR to point to your cross-compiler.
Build NTP
$ cd ../build/
$ ../src/ntp-4.2.6p5/./configure --prefix=/home/<your user>/workbench/ntp/final --host=$TARGETMACH
$ make
$ make install
Output
cd into the final directory and output its contents:
$ cd ../final/
$ ls
You should have the following directories:
bin
lib
sbin
share
Make sure the binaries are for ARM:
$ cd bin/
$ file ntpd
bash: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.16, not stripped
If you see something *similar* to above you're good to go ;-)
Lastly, move the contents of these directories, or the directories themselves if they do not already exist, to your custom Linux file system or dev board. Refer here for more info.
How To Build NTP for ARM
Intro
In this How To we are going to build NTP 4.2.6p5 with our GCC 4.8.2 cross-compiler. Be sure to start this build in a new terminal/tab to avoid any pollution from previous builds.

Gather the Sources
Now that we have a workspace created and we are currently in the src directory we can begin bringing down the sources and extracting them.

Build Environment
To make things a little smoother let's setup some environment variables:
$ export INSTALLDIR=~/workbench/gcc-4.8.2/arm $ export PATH=$INSTALLDIR/bin:$PATH $ export TARGETMACH=arm-none-linux-gnueabi $ export BUILDMACH=i686-pc-linux-gnu $ export CROSS=arm-none-linux-gnueabi $ export CC=${CROSS}-gcc $ export LD=${CROSS}-ld $ export AS=${CROSS}-asNOTE: Depending on whether you are using a cross-compiler built from my other wikis you might need to change INSTALLDIR to point to your cross-compiler.Build NTP
